Введение продукции

The mini-pleat HEPA filter uses microfine glass-fiber media folded into closely spaced pleats and stabilized with continuous thermoplastic beads instead of corrugated metal separators. Precise bead spacing prevents media-to-media contact and creates many narrow, uniform flow channels. A polyurethane seal bonds the single pack into an extruded anodized-aluminum frame, while optional faceguards protect the exposed surfaces. The high media area and shallow profile make this design suitable for cleanroom ceilings, laminar-flow equipment and compact terminal housings.

Основные характеристики

Hot-melt separators replace corrugated metal sheets and reduce both weight and airflow obstruction.

Closely controlled pleat geometry provides a large active HEPA area in a shallow panel.

Extruded aluminum cell sides keep the filter square while resisting normal cleanroom cleaning agents.

Polyurethane potting seals the complete media perimeter without leaving internal bypass paths.

Обеспокоенность клиентов продуктами

A mini-pleat HEPA panel must combine delicate high-efficiency media with precise spacing and reliable edge sealing.

Metal-separated HEPA cells are too heavy for dense ceiling-grid layouts.Separatorless hot-melt pleats and extruded aluminum sides reduce weight while retaining media area.

Closely packed media faces touch and create blocked channels.Continuous calibrated adhesive beads maintain exact spacing along every pleat.

Thin HEPA media tears when the panel is carried by its face.Recessed media and optional protective grids isolate the pleat surface from routine handling.

Leakage develops at the junction between the pack and aluminum extrusion.Four-sided urethane potting forms a continuous bond inside the frame cavity.
